option is mutually exclusive with TREE.
NODECOMPRESS Normally, VSTORE will decompress the data on a Store-compressed media
when verifying the files. However, when NODECOMPRESS is specified, the
files will not be decompressed. Instead, just the integrity of the raw data
read from the media will be checked. This results in a faster VSTORE of the
media, which just verifies physical consistency.
STOREDIRECTORY Specifies that VSTORE should use the supplied
directoryname when
looking for the disk store directory file. This option should be specified if
the disk directory file for this backup resides in a directory other than the
default path of /SYS/HPSTORE/store_dirs/. This file should be either a
directory file created by STORE, or a symbolic link pointing to one.
directoryname The name of the disk directory file to be used by VSTORE. It can be in
either MPE or HFS format. If it is not a fully qualified filename, it will be
qualified by the CWD. This file should either be a disk directory file
created by STORE or a symbolic link pointing to one.
PART[IAL]DB Allows VSTORE to verify individual database dataset files without
specifying the database's root or DBCon file.
THE FOLLOWING OPTIONS ARE AVAILABLE ONLY IF TURBOSTORE XL OR
TURBOSTORE XL II IS INSTALLED ON YOUR SYSTEM. TURBOSTORE IS NOT PART
OF THE FUNDAMENTAL OPERATING SYSTEM, BUT MAY BE PURCHASED
SEPARATELY.
For additional information on TURBOSTORE XL, refer to the
Store and Turbostore/iX
Manual
(30319-90001).
RESTORESET Specifies parallel and sequential backup devices. This option cannot be use
if the
vstorefile parameter is specified.
Consecutive tapes are specified in the following way:
< user ;RESTORESET = (* tape1 ,* tape2 ,* ta pe3 ,...)
This instructs MPE/iX to use only one drive at a time for the vstore
operation. When the first reel of tape is exhausted, VSTORE will shift to the
next available drive, leaving the first free for rewinding and changing
reels. Thus, at any given time,only one drive is occupied withthe VSTORE
operation.
Parallel devices are specified by
|;RESTORESET=(* tape1 ),(* tape2 ),(* tape3 )...|
In this example, all three tapes will be used in parallel during the
VSTORE operation.
A set of sequential tapes to be verified in parallel would be specified by
|;RESTORESET=(* tape1 ,* tape2 ),(* tape3 ,* tape4 )|
In this example, two tapes would be verifying at any particular moment,
while the other two are rewinding, permitting the operator to switch reels.
This option cannot be used if the
vstorefile parameter is specified.
